HCPL-M611

Logic Output Optoisolators Overview

The HCPL-M611 is a high-speed logic output optocoupler featuring a single channel in a 5-pin SO package. It combines a GaAsP LED with an integrated high-gain photodetector, providing LVTTL/LVCMOS compatibility. Key electrical parameters include a data rate of 10 MBd, isolation voltage of 3750 Vrms, and common mode transient immunity of 10 kV/µs. The device operates with a typical forward voltage of 1.5V, maximum input current of 20mA, and supply voltage range of 4.5V to 5.5V. Propagation delay is typically 75ns for both rise and fall times.

Logic Output Optoisolators Feature Summary

• Integrates a GaAsP light emitting diode with a high-gain photo detector for enhanced signal transmission.
• Features Schottky clamped open collector output to ensure system performance and LVTTL/LVCMOS compatibility.
• Provides high common mode transient immunity to maintain isolation integrity in noisy environments.

Logic Output Optoisolators Applications

• High-speed digital isolation in industrial communication interfaces
• Signal coupling between microcontrollers and peripheral devices
• Isolation in logic gate circuits requiring fast switching speeds

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., -500E) against the required packaging format, as it determines reel quantity. Confirm that the 5-pin SO package matches the PCB footprint. Ensure the operating temperature range of -40°C to 85°C meets the environmental requirements. Check for RoHS compliance status if restricted substances are a concern. Validate the isolation voltage rating against the circuit's safety standards.

Logic Output Optoisolators Selection Notes

Select this component when LVTTL/LVCMOS interface compatibility is required alongside high-speed data transmission. The 10 MBd data rate suits applications needing faster response than standard optocouplers. The 3750 Vrms isolation voltage provides robust protection for low-voltage logic circuits interfacing with higher potential domains. Consider the open collector output type for necessary pull-up resistor integration in the design.

Logic Output Optoisolators Part Context

This part belongs to Broadcom's HCPL series of optocouplers, designed for logic output applications. It is distinct from other series like HCPL-0211 or HCPL-0611 by its specific combination of speed, output structure, and pin count. The HCPL-M611 focuses on providing reliable isolation for digital logic signals rather than analog transmission or gate drive functions.

Logic Output Optoisolators Replacement Considerations

Direct substitutes may include HCPL-M611-000E, which shares identical electrical characteristics but may differ in packaging configuration. Verify pinout compatibility and thermal performance before swapping. No alternative part numbers are confirmed as direct replacements without datasheet cross-reference validation.
